Introduction

GB/T 25100, "Information and Documentation. Dublin Core Metadata Element Set," aims to construct a universal metadata set covering various types of resources.

This specification aims to standardize the description methods and metadata elements of digital information, thereby achieving a unified description of resources nationwide and promoting the development of digital resources.

The process of standardizing and regulating the source.

GB/T 25100 is proposed to consist of two parts.

---Part 1: Core Elements. The aim is to establish a set of core metadata elements suitable for describing cross-domain resources.

---Part 2: DCMI Attributes and Classes. The aim is to establish a complete cross-domain resource description vocabulary, including DCMI meta-elements.

According to the terminology, all attributes and classes in the main namespace.

The attributes and classes described in this document are intended to be used in conjunction with metadata terms in other compatible vocabularies within the context of the specified application outline.

Used. These attributes and classes are represented in the form of an RDF vocabulary and applied to related data. Each attribute and class has a global identifier.

The symbol is used for RDF data. It is also the creator of non-RDF metadata, in non-RDF scenarios such as XML, JSON, UML, and relational databases.

This thesaurus is used by ignoring global identifiers and term definitions in RDF form. Such users are interested in definitions, usage notes, and examples.

For natural language text, domain, range, sub-attributes, and subclass relationships are considered as usage suggestions.

1 Scope

This document constructs a thesaurus of Dublin Core Metadata Terminology (hereinafter referred to as "DCMI Metadata Terminology") to enable cross-domain resource description.

Description. It includes all attributes and classes in the DCMI metadata terminology main namespace (hereinafter referred to as "namespace terms/"), and related information.

See the 2012 DCMI recommended document "DCMI Metadata Terminology" (DCMI-TERMS and Appendix A). These attributes and classes...

The URI identifier (see Appendix B) is applied to the associated data.

This document is applicable to the description of various resources in the context of information resource organization.

This document does not provide implementation guidelines; these elements are typically defined or specified by the application framework based on local or community needs and policies.
